The K&N 50-2609 NextGen Cold Air Intake is a bolt-on replacement for the factory air box on 2017-2020 Ford F-150 and F-150 Raptor trucks with the 3.5L V6. The manufacturer builds it around a high-density polyethylene intake tube and a semi-enclosed NextGen air box meant to keep hot engine-bay air away from the filter. Its clearest advantage over stock is a larger, smoother air path and a washable, reusable High-Flow LIFETIME oiled cotton filter that you clean instead of replacing. Expect a modest airflow gain rather than a dramatic one. Owners on user forums frequently point out that the factory intake already draws from a cool position behind the grille, so buyers who want the gain should also weigh a cleanable filter, a tidier engine bay, and the sound change.
Fitment is listed by the manufacturer for the 2017-2020 F-150 and Raptor with the 3.5L V6 (F/I), so check your model year and engine before ordering. The kit uses a sealing bead that the manufacturer says is secured with one hose clamp, and the filter snaps in with Quick-Lock hardware, which keeps the hardware count low. The manufacturer states the whole system typically goes in under 60 minutes. Long-tail searches for this part usually involve 2017 F-150 3.5 EcoBoost cold air intake, Raptor twin-turbo V6 intake, K&N 50-2609 install, and washable oiled cotton EcoBoost air filter, and this listing covers those directly.
The manufacturer lists the 3.5L V6 for both the 2017-2020 Ford F-150 and the F-150 Raptor. Confirm your model year and engine against the manufacturer's fitment guidance before ordering.
The manufacturer materials I could confirm do not state whether a tune is needed. Check the install sheet or contact the manufacturer before assuming a plug-and-play installation.
The manufacturer describes the filter as washable and reusable. Owners on user forums say the cleanable design is a main reason they chose a K&N intake. Follow the manufacturer's care instructions for cleaning method and interval.
This is a bolt-on job that the manufacturer says typically takes under an hour. Download the installation instruction sheet for part 50-2609 from the manufacturer's product page and review it before you start, since the sheet is the authority on tools, torque values, and step order. Pay attention to the sealing bead and the single hose clamp, because a poorly seated coupling is the most common cause of air leaks on intake swaps. Check the mass airflow sensor connection and the throttle body coupling carefully. K&N's general install guidance for its intake kits describes moving the MAF sensor into the new adapter and securing the coupler, so confirm whether this NextGen kit follows the same sequence. After installation, inspect all clamps and connections for leaks and verify that the MAF sensor and wiring are not under strain.
